Abstract

L'invention porte sur un procédé de correction de pré-distorsion, un dispositif de correction de pré-distorsion, un émetteur et une station de base. Le procédé consiste à : sur la base d'un modèle de pré-distorsion numérique, traiter de manière non linéaire les signaux de transmission entrés afin d'obtenir des signaux de domaine temporel déformés multi-ordres; et obtenir des signaux de pré-distorsion d'un amplificateur de puissance d'entrée après traitement des signaux de domaine temporel déformés multi-ordres, le processus de conversion des signaux de domaine temporel déformés multi-ordres en les signaux de pré-distorsion comprenant un traitement de limitation de bande passante de telle sorte que les signaux de pré-distorsion de l'amplificateur de puissance d'entrée sont des signaux de pré-distorsion à l'intérieur de la bande passante préréglée. Les modes de réalisation de la présente invention peuvent non seulement assurer une précision de pré-distorsion mais également réduire les exigences sur la bande passante et le taux d'échantillonnage des canaux de rétroaction, permettant ainsi de réduire les coûts de pré-distorsion.
